The renewability of timber is its most important characteristic. A tree is cut down and used: it can be replanted. This sustainable process can go on indefinitely. The whole of the tree can be used utilising traditional and engineered timber techniques and biofuel, minimising waste.
Forests act as natural sinks for carbon across the world. Trees naturally lock away carbon during photosynthesis and release oxygen. This process slows as trees age, supporting a regular harvesting strategy to maximise forest carbon-capture capability. Timber grown in well-managed forests therefore helps the wider environment as well as creating a sustainable supply of building material.

Introducing wood
As a construction material, timber has a very distinct advantage over the alternatives, namely that it is a living thing and therefore a renewable resource. With the use of correctly managed forests, timber represents an excellent way of creating a more sustainable construction industry.
